We are building a multi-platform, multi-operating system, fully standards-compliant interoperable
wireless sensor network stack. Major standardization bodies have been looking at how wireless multi-
hop networks should operate reliably (IEEE 802.15.4E, IETF RPL), how they can integrate within the
Internet (IETF 6LoWPAN), and how utilities and end users should interact (OpenADR). All of these
standards are being finalized. The OpenWSN project aims at federating these standards into a fully-
functional protocol stack, at implementing these on a number of hardware and software platforms, and
at testing the resulting network in realistic residential, commercial and industrial facilities. All
of the software developed is open-source and accessible at http://openwsn.berkeley.edu/.
